    Good to know, thanks. But do you still need to remove the coolant hoses from the throttle body to remove it? And is removing the thottle body the best way to replace the cables?

    I replaced my cables earlier in the year, I didn't remove the throttle body or such, I don't remember it being hard at all, From memory I had the tank and rad off at the time for the valve Check...

    Who in Florida can tell me how these ride in the sand down there?

    Twist the throttle all the way, let the clutch out. Do not let off, it keeps the front light. If you let off or need to hit the brakes, you need to be making a turn, if you are going straight, it will auger in. Run one gear lower than normal to keep the RPM up.

    Just checking over my photos now I'm back at the bus, there's no issue getting to the cables on the throttle body:

    But you "might" have to unbolt the radiator and top radiator mounting bracket (you should be able to leave all the hoses attached), I have a feeling the cables are kinda pinched/retained by the bracket... I removed that bracket for a reason and I'm fairly sure it was to replace the cables...

    Yep. Ride it like a 125 2t and it does fine.

    This method really only works for relatively short sections of sand. If you're riding long distances in the sand, you can't safely keep it WFO forever.

    To ride long stretches of sand, keep it at a safe speed (though not too slow), keep the RPMs high, and be smooth. If you start getting squirrely and think you may lose it, that's when you really twist the throttle to lighten the front wheel... and that's why you keep the RPMs high (but don't keep the speed high - common misconception).

    How does that work with deep sand? Because I have always employed this particular technique quite successfully up until last trip in OR where out of nowhere I hit a sand trap with super fine sand, about 1 or 1 ft 1/2 deep. I tired to lighten up the front as usual, but I was either late, or not enough or maybe the sand was just too deep. It sucked the front in like glue, and I dumped it.

    The faster the better. Riding on sand is similar to skimming water, sand is just slightly more stable. The faster you go, the more on top you stay. The more it feels like regular solid ground.

    Another analogy is like running across the top of a bunch of bowling balls. If you are going fast enough, you only touch the top of each one for a millisecond and they are stable. If you go slow or stop on top of a ball, it will squirt out from under you.

    I dunno. Sometimes it'll just bite you! I wreck all the time offroad! lol

    I think there's a balance to be had. Too slow and you'll be unsteady and fall all the time. Too fast and you wreck too hard. Telling new (sand) riders to go as fast as they can is a recipe for disaster IMO. The faster you are riding, the faster you will fall. I don't know anyone who hasn't wrecked riding sand while learning. Nobody.

    Are you forgetting what bike this thread is about? The 24hp WR can’t go too fast in sand. I have tried. In fact, at full speed, as fast as the bike could go, nearly red line RPM, I still wanted more speed because I was sinking too much. If we were talking about a 50hp bike or one that is 100# lighter, I might agree with your statement.

    If you're riding long sections, you can get the WRR up to plenty fast a speed. Maybe not too fast for you, but too fast for someone inexperienced in sand.

    When I was in Florida in the spring, I could not make the bike go any faster than 50-55mph, and the front end was still plowing sand. I needed a bit more. I could still feel the front end wallowing in the sand. Every once and a while, I could get it over 60, maybe 65 and the front end would lighten up.

    Obviously this Ronnie guy is new to the sport of sand riding. He still hasn’t learned how to keep his bike straight on his jumps.

    The guys riding the WR250R’s were doing a good job though.
